The term 'EASY TO SAIL' can be summarized by the word 'YARE', which is a four-letter word meaning 'agile, sprightly, and easily handled'. This term is often used to describe a boat or ship that is easy to maneuver and control. YARE vessels are typically designed with a shallow draft, allowing them to sail in shallow waters, and they are also equipped with a large sail area, making them easier to sail.
